SPECIFICATION forming part of Letters Patent NO.. 726,152,.dated April 21, 1903. Application'filed December 1l?, 1902. Serial No. 135,558. (No model.)

by the cutter-bar-may be quickly thrown into or out of operative relation yto its driving mechanism.

With the above and other objects in View the invention consists in providing the powershaft with a slidable pinion which is adapted to be thrown into or out of engagement with4 a pinion on the cutter-bar-operating shaft by means of an eccentric secured to a revoluble spindle andjhaving means for holding it inY the position to which lit is moved.

The invention also consists-in the further novel construction andcombinations of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showingthe preferred form of my invention, and in which Figure 1 isal plan view of the cutter-bar-l operating m'echanismand' its shifting device,

the vertical cutter being shown in section. Fig. 2 is a section-'on line 2 '2,Fig. 1; and Fig. 3 is a detaill view ofthe shiftin g eccentric and its spindle. Y

Referring to' the figures by numerals of reference, lis the frame of the machine, having a traction-wheel 2, mounted on a short shaft 3, extending therefrom. The inner periphery of the traction'- wheel is provided with gear-teeth 4, adapted to mesh with a gear 5,'

securedto and revoluble with a power-shaft 6, slidably .mounted in :suitable bearings 7 and Supon the frame 1. Those portions of shaft 6 journale'd in the bearings are preferably reduced in diameter, as shown at 9-, in order to limit the longitudinal movement of the shaft.

A collar 10 is arranged on shaft 6 and normally contacts with the periphery of a disk 11, eccentrically mounted at one end of a spindle 12, arranged at right angles to said shaft 6.^ Suitable bearings 13 are provided for thespindle, and any desiredv means, as a reduced wear-surface 14, is provided for preventing longitudinal vmovement thereof. A ratchet 15 is secured to the spindle 12, adjacent to the eccentric 1l, and is engaged by a spring-pawl 16, which serves to prevent the revolution of-the spindle except in one direc- 6o tion. A knob 17 or other suitable means is arranged at the outer end of spindle 12, lwhereby the same may be readily turned by hand. y

A pinion 18 is secured to and revoluble 65 with the shaft 6 and bears upon one end of a spring 19, coiled about shaft6, and bearing at its opposite end upon the bearing 8. The spring serves to hold the shaft 6 normally pressed forward, with its collar 10 in contact 7o with the eccentric 11. It also holds gear 18 normally in engagement or mesh with a similar gear 20, secured to a short Shaft 2l, arranged at right angles to shaft 6 and j ournaled in suitablefbearings 22. A disk 22a is secured 75 to this shaft and Yis connected to the recipro Veating cutter-bar 23 by means of a pitman r24. Y Any other desired means, however, may vbe employed for transmitting power from shaft 2lI to the cutter-bar.

' It' will be understood that gears 5 and 18 and their shaft '6'are revolved continuously duringtherevolution of the traction-wheel 2. Motion is imparted to cutter-bar 23 from this shaft through gears 18 and 20, shaft 21, 85 and pitman 24. When, however, it is desired to disconnect the cutter-bar and rendel it inoperative during the revolution of the traction-wheel, the spindle12 is partly turned vby means of knob 17, causing the eccentric 9o 11 to swing against collar 10 and force it and the shaft 6 longitudinally, thereby compressing spring 19 and removing gear 18 from .mesh with gear 20. The pawl 16 holds the eccentric in this position.- When the revolution of the eccentricis continued, the spring `19 returns the parts to their normalpositions.

during the revolution of the traction-wheel from which it receives power.

In the foregoing description I have shown the preferred form of my invention; but I do not Wish to limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacricing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having` thus fully described the invention, what I claim is- The combination with a cutter-bar-operating shaft having a pinion thereon; of an internally-toothed traction-Wheel, a longitudinally-movable power-shaft, a gear thereon meshing with the teeth in the traction-wheel,

a pinion upon' said power-shaft, a spring' adapted to hold said pinion and the pinion of the cutter-bar-operating shaft normally in mesh, a collar upon the power-shaft, a revoluble spindle at right angles to Said shaft, an eccentric thereon adapted to bear upon the collar and impart longitudinal movement thereto and to the power-shaft, a ratchet- Wheel upon the spindle, and a spring-pawl engaging said Wheel and adapted to prevent movement of the eccentric in one direction. In testimony whereof I affix my signature in presence of two witnesses. l
